i've oft thought about replacing the 4.0 straight-6 in my Jeep when (and if ) it ever dies (i swear that engine was built to run eternally!)
but yes - i (and i'm sure "we") would love to see some photos of your V-8 conversion in your Wrangler, if ya don't mind sharing

I'll try not to hijack the thread here but...
The conversion was done at Mad Dog Service up on Port Chester. They do amazing custom work. I had blown a 4" hole on the side of my block and felt it was the time to go a little bigger. I had already had the nv4500 and atlas from a couple years back when I went through my 2nd np231. Labor etc. can add up but I still don't get how an atlas is cheaper than a re manufactured np231 from a dealer. The nv4500 is very strong but it is a truck box so it appreciates a slower shift or a double clutch.
In the picture from below you can see two sets of manifolds with the driver side bank crossing under the bell housing. With everything under the hood, you can't see much of the engine (especially with the intake tube bending around through the cowl). I have a couple photos but everything is pretty tight under the hood so there isn't really much you can capture. In the last picture, you can tell the hemi was the one that came in the trucks because the air intake is at the rear of the motor. The car had the throttle body at the front. There is a 1" body lift required to clear the firewall and the transmission and transfer case shift about 3" forward from there original position. The computer has to be swapped along with the gas tank / emissions equipment from a 2005 or newer jeep so you don't have a constant engine light on. My Jeep was a tricky install because most of the hemi's are going in with automatic transmissions. I wanted to keep the NV4500 and every conversion part is geared towards the automatics so pretty much nothing bolted right up. It was a lot of parts to make it work but it certainly has given the TJ a whole new character.
